Aseptic meningoencephalitis can mimic transient ischemic attacks (TIAs). Recognizing subtle signs like sensory hemisyndrome and cognitive deficits is crucial for accurate diagnosis and appropriate treatment, differentiating it from stroke.
Area of Science:
- Neurology
- Infectious Diseases
- Neuroimaging
Background:
- Transient ischemic attack (TIA) is a common neurological emergency.
- Accurate differential diagnosis is critical to guide appropriate management.
- Meningoencephalitis can present with symptoms overlapping those of TIA.
Purpose of the Study:
- To identify meningoencephalitis as a mimic of TIA.
- To suggest clinical indicators for differentiating meningoencephalitis from TIA.
- To emphasize the importance of considering meningoencephalitis in TIA-like presentations.
Main Methods:
- Observational study of patients presenting with TIA-like symptoms.
- Analysis of clinical presentations, cerebrospinal fluid (CSF) findings, and brain MRI results.
- Review of diagnostic work-up and treatment outcomes over a 9.75-year period.
Main Results:
- Seven cases of meningoencephalitis mimicking TIA were identified among 790 TIA patients.
- Common presentations included acute sensory hemisyndrome and cognitive deficits.
- CSF analysis revealed lymphocytic pleocytosis and normal glucose index; MRI showed meningeal thickening.
Conclusions:
- Aseptic meningoencephalitis should be considered in the differential diagnosis of TIA.
- Lumbar puncture threshold should be individualized based on clinical factors and imaging.
- Early recognition and appropriate management are vital for patients with TIA-like symptoms.
